carrier 30gh flotronic 1990

Hello gents
,hope all is well. I need to know firstly is it possible to convert old carrier 30gh flotronic to txv? and if so how to go about it. the 30gt has a setpoint for txv or exv , the 30gh doesnt appear to . I read somewhere about a kit for retro, eprom required? Site wants to convert to 407c/poe, 1990 chiller, I guess im also wondering if its possible to install txv and lls and ignore exv modules? or would that bring up alarms not seeing the windings? other option upgrade exv and drivers? that maybe quite pricey, thanks for input! stan

ok I will, pt relationship is close enough , if only they had parameters lik 30gt and 30gb option of exv/txv I would put 407c txvs in w LLsolenoids.
fingers crossed , less than 2 years life left for this chiller stan
